I noticed this issue when a --merge sort was killed because of oom. It shouldn't.

Sort utility built from vanilla coreutils-8.4.tar.xz was not affected.

Sort utility built from coreutils-8.4-31.el6.src.rpm fails and valgrind show that it was caused by coreutils-i18n.patch

The issue was caused by calls to mbsrtowcs, wcsrtombs which will modify *src to NULL causing later free() to fail.

	Subject: [PATCH] emulator: load libGLES_android.so from /system dir

	Existence of /vendor/lib64/egl/ will cause qemu.gles to be set to 2.
	Which will result in the libGLES_android.so to have no chance to be
	loaded at all. It's part of the frameworks anyway, so treble should not
	be an issue.
